Explanation: Dadra and Nagar Haveli, along with Daman and Diu, were territories under Portuguese colonial rule until they were integrated into India in 1961. This integration was a significant event in the post-independence era of India, marking the end of European colonial rule in the region.
To understand the historical context, it is important to note that the Portuguese presence in India dates back to the 16th century. They established several enclaves along the western coast of India, including Goa, Daman, and Diu. These territories were not part of the British Raj and remained under Portuguese control even after India gained independence from British rule in 1947.
The integration of Dadra and Nagar Haveli into India was part of a broader movement to reclaim territories that were under colonial rule. The Indian government, under Prime Minister Jawaharlal Nehru, initiated a campaign to liberate these territories. The liberation of Goa, Daman, and Diu took place in December 1961, following a military operation known as Operation Vijay. This operation was a significant moment in Indian history, as it marked the end of all European colonial rule in India.
The territories of Dadra and Nagar Haveli were unique in that they were not directly administered by Portugal but were under the control of the Portuguese government through the local rulers. The integration of these territories into India was a complex process involving diplomatic negotiations and, in some cases, military intervention.
Understanding the history of Dadra and Nagar Haveli is crucial for comprehending the broader context of India's struggle for independence and the subsequent efforts to unify the country under a single sovereign government. This historical event is often examined in the context of India's post-independence territorial consolidation and the end of colonialism in the region.
In summary, the correct answer is Portugal, as it was the colonial power that ruled Dadra and Nagar Haveli until the territories were integrated into India in 1961. This event is a significant part of India's colonial and post-independence history.
